Abstract
A method for recharging an electric vehicle having an electric battery for powering a vehicle drive system is provided. The method includes recharging the electric vehicle during a first period at a first electrical power and recharging the electric vehicle during a second period shorter than the first period at a second electrical power higher than the first electrical power. The recharging includes delivering coolant to the electric vehicle to cool the electric battery during the second period. Other methods of recharging an electric vehicle are also provided.
